Hi and Welcome to TSF!

I'd stick with a known-name brand PSU like Seasonic, XFX, and Antec.

I agree. You don't buy a new Porsche or BMW then fill it up at the corner Tobacco and Bait shop and expect you are feeding the engine good quality "clean" fuel.

So stick with well known reputable brands.

At the very least, get a power supply that is 80 PLUS certified. 80 PLUS certified PSUs are required to have fairly linear efficiencies. This is important because a computer's power demands range from very little when idle to near maximum when taxed (such as during heavy gaming). 80 PLUS certifications require PSUs run at or near peak efficiency of at least 80% regardless the load or power demands.

Non-linear PSUs typically have a narrow "peak" efficiency when the load is somewhere between 50 and 90% of the PSU’s maximum capacity. And that peak is typically around 70% efficient, or less.

That means at best, for every 100W the power supply pulls from the wall, 30W will be wasted in the form of heat!

And then the efficiency typically drops dramatically above and below that peak for even more wasted energy and more heat. The efficiency "curve" is a steep "bell curve" while a quality 80 PLUS certified supply's curve will be relatively “flat” (linear) across the entire expected range of loads.

I generally recommend power supplies that have earned 80 PLUS "Gold" certification or better. While these highly efficient supplies cost more up front, you will easily recoup your investment (and more) in lower energy costs over the lifespan of the power supply. And you will be feeding your computer better quality power too which results in less strain on the regulation circuits of the connected components.

At least go for "Bronze" certification.
